[Pharyngitis produced by Arcanobacterium haemolyticum].

Arcanobacterium haemolyticum (A.h.) was recovered from 0.43% of throat cultures of 3715 patients with sore throat, scarlatina and various skin rash. In a 57.90% patients A.h. was the only bacterial pathogen isolated, while in the remainder beta-haemolytic streptococci, Haemophilus and S. aureus were also detected. beta-haemolytic streptococci were much more frequent than A.h. in the throat cultures (26.83%). All A.h. strains were of the smooth type based on colony morphology and the ability to ferment sucrose. The strains were susceptible to penicillins, cephalosporins, erytromycin and resistant to trimethoprim-sulphamethoxazole. Pharyngeal injection in 89.47% and exanthem in 78.90% were the most common signs present to the patients.

[Rapid diagnosis in tuberculosis by using the MB/BacT system].

428 clinical samples were examined by the MB/Bact system and by inoculation on "Tebeglut" medium. 43.9% of the samples were positive for Mycobacterium sp. when examined by MB/BacT system and 29.6% when cultivated on Tebeglut. The reported percent of positivity (43.9%) is highly superior if compared with those reported in other countries: Great Britain (9.1%), France, (7.0%). The MB/BacT system is much more effective in detecting mycobacteria if compared with Tebeglut cultivation, mainly in two categories of samples: those with no evidence of AARB and those with fewer than 10% AARB. From 156 Mycobacterium sp. isolated in MB/BacT system, 88.5% were M. tuberculosis, the others being atypical mycobacteria.
